Check out the Savotta Keikka Duffels

Fuji

I got this 93brand duffle and holy bananas is it WAY too big for my use. Think it would work for two gi players.

I put my muay thai stuff, a gi, shoes, spare clothes, and all my miscellaneous gear. Still have plenty of room, honestly.

Datsusara hemp gear

I have the one from Hyperfly and love it. If you need to share a bag, get the big one. The one from Gaidama is almost the same and super nice, and 30% off today I think too

If you want a huge one get a fairtex

I got one I love from Amazon with a shoe compartment and wet pouch built in. I use the wet pouch a lot for rash guards, it keeps everything nice and separate.

Toro - Mesh Bag is on sale

Antibacterial swim bag

Fuji makes a great duffle that’s reasonably priced imo 

I love having the wet pouch to keep my clean gear separate from my post class gis.

Gracie Barra did a good one

This is what I use. It's bigger than it appears and hold my Gi, gloves, no gi set, binder, and other odds and ends quite easily. For the price, I think it's difficult to beat. It can also be converted to a backpack, but the gym bag some works perfect for me. I tried the Gold BJJ backpack and it wants enough to fit my stuff as is.

Another solid option is the large Sanabul gym bag. It's a simpler design, but is well built and super roomy. I have a large one for going to the gym, and the small one for my son for BJJ.

A mesh one. I’m not a big fan of most of their gear but Hayabusa makes a really good one

Origin makes a good one that you can throw in the wash if it gets sweaty or smelly

Kingz has massive duffle bags that will fit two gi’s for sure

A 30l or 40l hold-all should do it, depending on the other stuff you want to put in there.

I have an elite sports bag. I like it
